AMD Ryzen 7 5700G vs AMD Ryzen 7 5700X Comparison

Where Each One Wins

The benchmark data splits these two AMD Ryzen 7 parts into very distinct roles. The Ryzen 7 5700X wins 21 of the 23 recorded head-to-head tests, while the Ryzen 7 5700G claims only 2 victories. That near-sweep makes the 5700X the clear choice for compute-heavy workloads, but the two 5700G wins hint at where the G-series part has its own niche.

The 5700X dominates in multi-threaded and single-threaded CPU work. Its largest margins come in PassMark's find prime numbers test, where it scores 119 against the 5700G's 59, a 101.7% advantage. That is not a small gap; it points to a substantial difference in how efficiently the two chips handle certain integer workloads. The 5700X also leads by 33.8% in PassMark physics (1337 vs 999) and by 10.5% in Cinebench R15 multi-core (2329 vs 2107). These are meaningful deltas, not rounding errors.

The 5700X also wins every 3DMark test, though by smaller margins. In 3DMark 16-thread, it scores 6858 against 6629, a 3.5% lead. In 3DMark single-thread, it scores 921 against 899, a 2.4% edge. The 5700X is consistently ahead in these mixed workload tests, but the differences are modest compared to the prime number gap.

The 5700G's two wins come in PassMark data encryption (20325 vs 20198, a 0.6% lead) and PassMark extended instructions (21847 vs 21755, a 0.4% lead). These are narrow margins, effectively a tie in real-world terms. But they show that the 5700G is not universally slower; in specific instruction-heavy or encryption tasks, it can edge ahead. The practical takeaway: if you need maximum raw CPU throughput, the 5700X is the pick. If you need integrated graphics and are willing to accept slightly lower CPU scores, the 5700G has its place.

Architecture Differences

Both processors are built on Zen 3 architecture and use the 7 nm process from TSMC, but they are different dies with different priorities. The 5700X uses the Vermeer codename, while the 5700G uses Cezanne. That codename difference reflects a fundamental design split: the 5700X is a pure CPU with no integrated graphics, while the 5700G includes Radeon Vega 8 graphics.

The transistor counts tell the story. The 5700X packs 4,150 million transistors on a 74 mm² die. The 5700G contains 10,700 million transistors on a 180 mm² die. The larger die is largely due to the integrated GPU, which adds substantial silicon area. That extra hardware means the 5700G cannot devote as much die space to CPU cache.

Cache allocation differs sharply. The 5700X has 32 MB of shared L3 cache, while the 5700G has only 16 MB of L3. Both have 64 KB of L1 per core and 512 KB of L2 per core, but the halved L3 is a significant architectural disadvantage for the 5700G in cache-sensitive workloads. The larger L3 on the 5700X helps explain its strong lead in tests like PassMark find prime numbers, which often benefits from larger cache footprints.

The PCIe implementation also differs. The 5700X supports Gen 4 with 20 lanes (CPU only), while the 5700G supports Gen 3 with 16 lanes (CPU only). That means the 5700X offers both a newer PCIe standard and more lanes, which matters for users connecting high-bandwidth devices like NVMe drives or discrete GPUs. The 5700G's older PCIe Gen 3 interface is a limitation for expansion.

Memory support is identical in type and bandwidth: both support DDR4, dual-channel memory, and 51.2 GB/s bandwidth. ECC memory support differs, however. The 5700X supports ECC, while the 5700G does not. That makes the 5700X more suitable for workstation or server-style builds where data integrity is critical.

The integrated graphics on the 5700G is the defining feature that the 5700X lacks. With Radeon Vega 8 built in, the 5700G can output video without a discrete GPU. The 5700X requires a separate graphics card. This is the core trade-off: the 5700X offers better CPU performance and more cache, while the 5700G offers a complete system in one chip.

The base clock difference is notable: the 5700G runs at 3.80 GHz base, while the 5700X runs at 3.40 GHz base. Both boost to 4.60 GHz. The higher base clock on the 5700G does not translate into benchmark wins, which underscores the impact of the 5700X's larger cache and different die design.

Head-to-Head Benchmarks

The head-to-head data shows a clear pattern: the 5700X leads in nearly every category, with the largest wins concentrated in specific CPU-intensive tests.

The most striking result is PassMark find prime numbers. The 5700X scores 119, while the 5700G scores 59. That is a 101.7% delta, meaning the 5700X is more than twice as fast in this workload. This test is heavily dependent on cache performance and integer execution, and the 5700X's 32 MB L3 cache versus the 5700G's 16 MB likely explains the massive gap.

PassMark physics is another standout. The 5700X scores 1337, the 5700G scores 999, a 33.8% lead for the 5700X. Physics simulations often stress memory latency and cache behavior, areas where the 5700X's architecture appears better suited. Cinebench R15 multi-core shows a 10.5% advantage for the 5700X (2329 vs 2107), confirming that the 5700X scales better across all cores under sustained load.

Geekbench multi-core results show an 8.3% lead for the 5700X (10779 vs 9950), and PassMark multithread shows a 9% lead (26612 vs 24419). These are consistent, moderate gains that point to the 5700X being the stronger all-around CPU for threaded applications.

Single-threaded tests also favor the 5700X, though by smaller margins. Geekbench single-core shows a 6.4% lead (2016 vs 1894), Cinebench R15 single-core shows a 4.3% lead (253 vs 242.5), and PassMark single-thread shows a 3.1% lead (3385 vs 3283). Even in lightly threaded tasks, the 5700X holds an edge.

The 3DMark results are closer. The 5700X leads by 3.6% in both 2-thread (1821 vs 1758) and 4-thread (3512 vs 3389) tests, by 3.5% in 16-thread (6858 vs 6629), and by 3.4% in max-thread (6850 vs 6627). The 8-thread test shows the smallest 3DMark margin at 2.1% (5768 vs 5648). These results suggest that in mixed or gaming-like workloads, the two chips are relatively close, but the 5700X still comes out ahead.

The 5700G's two wins are narrow. PassMark data encryption shows 20325 vs 20198, a 0.6% edge for the 5700G. PassMark extended instructions shows 21847 vs 21755, a 0.4% edge. Both are within noise and unlikely to matter in real-world use, but they do indicate that the 5700G's design is not universally inferior.

Cinebench R23 multi-core is one of the closer multicore results: 13184 for the 5700X versus 12830.5 for the 5700G, a 2.8% delta. Cinebench R23 single-core is essentially tied at 1499 versus 1494, a 0.3% difference. These modern rendering workloads show the 5700X ahead, but not by a dramatic amount.

Overall, the data paints a clear picture. The 5700X is the superior CPU for raw performance, with decisive wins in cache-sensitive and physics-based tests, and solid but smaller leads in most other areas. The 5700G counteracts this with integrated graphics and a higher base clock, but the benchmark record shows that the 5700X is the stronger processor in almost every measurable CPU task.
